Thumbnail Filmstrip of Glass Fiber Filter Paper Discs, 1.5um, 125mm, Binder-Free, Nonsterile, 100/Pk Images
Featuring a binder-free borosilicate glass microfiber depth medium, these 125 mm diameter filter discs deliver a 1.5 um nominal particle retention for demanding gravimetric and clarification work. The naturally hydrophilic, binder-free construction avoids extractables that can interfere with weighing and analysis, while the deep three-dimensional matrix captures fine particulates and provides high loading capacity at fast flow rates. Each disc is supplied nonsterile in packs of 100.
Key Glass Fiber Media Characteristics
- Nominal retention: retains fine particulates down to a 1.5 um nominal rating, capturing very small suspended solids.
- Binder-free borosilicate: pure glass microfiber free of binders, minimizing extractables for accurate gravimetric and analytical results.
- Naturally hydrophilic: wets readily with aqueous samples for consistent, rapid filtration.
- Depth structure: the three-dimensional fiber matrix provides high dirt-holding capacity and fast flow under heavy particulate loads.
- Chemically robust: biologically inert, autoclavable, and resistant to oxidizing agents and weak acids.
Key Construction Characteristics
- Format: 125 mm diameter circular disc.
- Material: 100% borosilicate glass microfiber, binder-free.
- Sterility: supplied nonsterile.
- Pack: 100 discs per pack.
The depth medium maintains reliable particle capture and rapid throughput even with heavily loaded aqueous samples, protecting downstream membranes and preserving sample integrity. The binder-free borosilicate structure supports demanding gravimetric methods where extractable interference must be avoided.
